SIEMENS "adapt" statement (PPCL)
I'm quite familiar with how to write a LOOP statement but have had very little exposure to the newer "ADAPT" statement. Does anyone have anything in writing, perhaps a section out of a training manual that can display to me exactly how this command line works and how to write it? Has a new section been added to the PPCL manual to include this statement? If so, can someone e-mail me the section?
Also, how does this statement differ from a LOOP statement?
Thanks in advance.
Self tuning PID loop.
Example of ADAPTS
2000 C ADAPTS CONTROL LOOP STATISTICS (LOGICAL
2002 C FIRMWARE) STATIC PRESSURE CONTROL
2004 C DIRECT CONTROL LOOP
2006 C INPUT = %X%SSP
2008 C Output = %X%LP1
2010 C SETPOINT = %X%SSS
2012 C SAMPLE TIME = 1 SECOND
2014 C GAIN = %X%KC
2016 C TIME CONSTANT = %X%TC
2018 C REVERSE ACTING FLAG = 1
2020 C LOW LIMIT OF INPUT = -0.1
2022 C HIGH LIMIT OF INPUT = 5.0
2024 C LOW LIMIT OF OUTPUT = 0.0
2026 C HIGH LIMIT OF OUTPUT = 100.0
2028 C ERROR DEADBAND = %X%DB1
2030 C NOISY PROCESS VARIABLE = %X%NP1
2034 C ERROR REPORT POINT = %X%ERR
2036 IF (%X%RP1.LT.%X%LP1) THEN GOTO 2042
